Webster, Thanks for the (quick) reply. I googled around to see examples of douglas fir coated in boiled linseed oil, and it looks pretty nice. That is all that it needs? No need for some sort of poly-whatever as a second step? (Like I said, I'm new to this whole thing, so don't know much.)
One site that talked about finishing with the boiled linseed oil that you recommend also advised a second step where "then the entire table is then hand rubbed with wax." What wax is being referred to there and what does that do? Would you recommend that?
Also, if you like the idea for the "bench," as you alluded to, I got the idea from this guy:
(And I was able to source the piping for less $$$ than he notes, so it was substantially cheaper.)
One last thing: I am in Southern California, and I think I just read online that certain finishes/stains are outlawed here, so certain things I wouldn't be able to buy.
There are a few tiny cracks in it, but at the lumber yard I worked with the guy to find an 8' piece that was pretty clean. Should I do sanding on the ends before finishing? (Sorry if these questions are amateur!)
